Information
Check whether the use of residual current protective devices with increased trigger current as well as with short-time
delayed or delayed switch-off trigger characteristics are permitted in your application.
DANGER!
Electrical voltage! Risk of fatal injury due to electric shock!
Leakage and residual currents with a DC current component can restrict the functionality of type A and AC residual current
protective devices.
▪
Always follow the installation instructions for the protective devices you are using.

Housing grounding
You connect the grounding conductor to the drive controller over terminal X10.
Additional requirements for protective equipotential bonding apply in the event of ground leakage currents > 10 mA. At
least one of the following conditions must be fulfilled:
§
The grounding conductor must have a minimum cross-section of 10 mm² Cu over its overall length
§
If the grounding conductor has a cross-section of less than 10 mm², a 2nd grounding conductor must be provided with
a cross-section of at least the same size up to the point at which the grounding conductor exhibits the minimum cross-
section of 10 mm²
A grounding bolt is mounted to the devices for connecting the 2nd grounding conductor.
Note the tightening torque of 4.0 Nm.
